WASHING MACHINE.

Application filed July 3,

To aZZ'whom it may cmwem:

Be it known that I, O'rro BUTZBACH, a citizen of the United States, residing-at Chicago in the county of Cook'and State of Illinois, have invented certain new and useful Improvements in WashingMachines, of which the following is a specification.

This invention relates to washing ma- .chines.

It will be explained as applied to the clothes receptacle of a laundry washing machine.

One of the objects of the invention is to provide-an improved washing machine.

Another object is to provide a clothes receptacle which will produce increased agitat ion of the clothes, more violent circulation of water through the clothes, and a more rapid interchange of water between the outside and the inside of the receptacle.

Other objects and advantages will hereinafter appear. 4

An embodiment oftho invention is illustrated in the accompanying drawing, wherein Fig. 1 i s a perspective of a clothes receptacle with the door open.

Fig. 2 is a section on the line 2-2 of Fig. l, with the water tub of the Washing machine also shown in section.

Fig. 3 is a perspective of one of the partitions of the receptacle, and

Fig. 4 is a perspective of one of the agitating ribs or buckets with which the receptacle is provided.

In general, the laundry washing machine comprises a stationary outer water tub 5 and a movable innerclothes receptacle 6. The receptacle may be journaled to the end walls of the tub and rotated or oscillated by any suitable source of power, such as a motor and belting or gearing. The walls of the receptacle are provided with holes through which water may pass back and forth between the tub and the receptacle.

In order to increase the tumbling of the clothesand the churning of the water the receptacle is provided with a series of inwardly projecting open backed longitudinallyextending bucket like ribs 7 of substantially V-shaped cross-section.

8, each of which may be made of one piece of suitablesheet metal. Each head has an outwardly dire'ctedcircumferential flange 9- 1923. Serial No. 649,233.

to which the generally cylindrical side wall of tub 5.

The side wall of the tub is composed of a series of curved perforated sheet i'uetal panels 11 and interposed ribs 7. "The ends of panels 11 are secured to head flanges 9 by suitable means such as rivets 12. in the receptacle illustrated there are four fixed curved panels 11 and five ribs, although, of course, the number may be varied as desired. An additional curved panel forms a door 13. through which clothes may be inserted into and removed from the receptacle. A piano hinge 14 serves to secure'one edge of door 13 adjacent the edge of onetof the fixed panels. Any suitable lock 15 may be used to hold the door shut. "Thedoor may he recnforced by an angle bar 16 along its free edge and transverse angle bars 17.

clearly shownin Fig. 1, to receive the edges of the partitions to be hereinafter described,

when the door is closed.

The receptacle is divided transversely into compartments by single piece sheet metal partitions 20. Each partition has a flange or series of flange sections 21 to which panels 11 are secured by suitable means,

such as rivets 18. Each partition is provided with radially extendlng somewhat V- shaped notches 23 into which ribs 7 fit. Each partition also has a hole 24 located a short distance inside of the bottom of each notch 23. Each partition may be provided with a notch 25 to receive angle bar 16, when the door is closed.

Each rib 7 may be formed from a single piece of perforated sheet metal bent into a trough as clearly shown in Fig. 4. The upper edges of the ribs are bent abruptly outwardly to form flanges 26. The ends of rib flanges 26 fit upon the outer surface of head flanges 9 and are secured thereto by suitable 4 by bolts, rivets, welds or other suitable Receptacle ,6 is formed with two heads When the partitions, curved panels and 110 interposed trough shaped ribs are assembled in position the edge of each partition adjacent the bottom of each groove extends through the corresponding slot 27 of the respective partition far enough to expose holes 24 as most clearly shown in Figs. 1 and 2. Long bolts or truss rods 28 extend through holes24; in each partition within the confines of the apex of the rib, and through heads 8 and assist in tieing or securing the entire, structure together and to strengthen and brace the same. L 'lhdperforated walls of the clothes receptacle permit Water to pass therethrough. Ordinarily, however, a relatively smooth perforated w-all does not permit sufficient v interchange of water ,to produce efficient washing. lVith the, improved receptacle herein shown, the long perforated open backed trough shaped ribs form water buckets. These buckets not only forcibly project the water from the tub into'the r e-.

near thetop, allow the same to drop down upon the water in the receptacle. The open backed perforated troughs therefore not only greatly facilitate the agitation of the clothes and the circulation of water therethrough but provide a greatly increased interchange of water between the tub and receptacle.

The receptacle ma be made of rust and detergent resistant sheet metal and its walls may be so smooth that no injury can be done to the clothes being washed therein.

Having described my invention what I claim as new and desire to secure by Letters Patent, is

A cylindrical receptacle for a Washing machine comprising a pair of flangedfhea'ds, a plurality of partitions in spaced relation with said heads for dividing the rece tacle into a plurality of compartments, sai titions having V-shaped notches in its periphery, perforated" slotted V-shaped baffle members extending between said heads and resting in the notches of said partitions, said partitions extending into said slots, and. tie rods passing through said baffle niembers and partitions.

vIn testimony whereof I hereunto subscribe my name.

OTTO BUTZBACH.
